The present invention relates to an extended data service (hereinafter referred to as an EDS) transmitted from a broadcasting station when a user selects a sleep function or reserved viewing in a television having a caption / text broadcasting receiver. The present invention relates to a timer setting method of a television using an EDS capable of setting a timer using included program length / elapsed time information.

In recent years, with the widespread use of television and the fact that almost all homes have at least one television, television has become an important carrier of information to the general public, leading the technologically advanced countries of the United States and Europe. Caption / text broadcasting, which was started by using the same method, can be regarded as a realization for information transmission using such a television.

In addition, since caption / text can transmit various information as well as contents related to television broadcasting, it has been the subject of many studies on how to use TV caption / text broadcasting as a medium for transmitting various information to related parties and developers. have.

At the same time, the necessity of standardization in caption / text information transmission in order to prevent disordered overflow of information due to the complexity and diversification in using such caption / text broadcasting for information transmission, and finally in 1992 On October 22, the data to be transmitted to the caption / text broadcasting line, that is, the specification of the contents and transmission method of the EDS, was proposed and released in draft EIA-608. In the future, the EDS using the caption / text broadcasting was draft EIA. There is a high possibility of transmission to a television in accordance with the specification of -608.

The present invention uses the EDS data transmission method according to the draft EIA-608 standard as described above, and in particular the information on the length / elapsed time of the television program in the contents of the EDS data is carried out after a certain time from the present time. It is an object of the present invention to provide a method for setting a timer of a television using an EDS configured to use a time data for eliminating a separate timer.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram showing the configuration of an apparatus for carrying out the present invention, wherein in a television including a caption / text room receiving apparatus, a broadcast signal containing a caption / text transmitted from a broadcasting station is once tuned in a television. After being received by the unit 10 and passing through the intermediate frequency IC 20, it is output to the image processing unit 30 for various processing for output to the screen of a television, and at the same time in field 2 of the 21st vertical blanking period. The loaded EDS data is sliced by the data slicer 40 and sent to the decoder 50.

The EDS data extracted by the data slicer 40 is decoded by the caption decoder 50 and applied to the microcomputer 60.

At this time, the microcomputer 60 drives the program according to the present invention based on the input data code.

2 is a flowchart illustrating a process flow of a program for driving the microcomputer 60.

As shown in FIG. 2, step (A) of checking whether an input control code is decoded to indicate that EDS data is being transmitted, and then decoding the input carrier code to indicate that the EDS data represents a program length / elapsed time. Step (B), if the step (A, B) confirms that the program length / elapsed time information is determined, whether the measurement mode of elapsed time is turned on, that is, the user sleeps or reserves the function of the television. (C) checking whether it is turned on; if the measurement mode of elapsed time is turned on in step (C), comparing program length / elapsed time (D); It consists of a step (E) to perform.

Referring to the timer method of the television using the EDS data of the present invention configured as described above in detail based on the action and effects are as follows.

First, the method of transmitting EDS data proposed and proposed by draft EIA-608 is briefly described. EDS data is transmitted along with caption / text data in the 21st vertical blanking period of a television broadcast signal. EDS data uses only field 2, while both 1 and 2 are used.

In addition, the EDS transmission is composed of a control code for indicating the start or transmission of the EDS transmission, a carrier code for informing information about the content of the data to be transmitted, and an actual data code.

Details are shown in detail in draft EIA-608. Here, when describing the code used in the present invention, the control codes indicating that the EDS information is being used or the start or transmission of the EDS transmission are 01h and 02h, and EDS data. Is an EDS carrier code indicating that the program length / elapsed time information is 02h, and the EDS data code for indicating the current time is composed of 2, 4, or 6 character codes.

The EDS configured as described above is serviced by the transmitting broadcast station using field 2 during caption / text data transmission. Like the broadcast signal, the EDS is received by the tuner unit 10 and frequency filtered by the intermediate frequency IC 20. Only the EDS data is sliced by the slicer 40 and sent to the decoder 50.

The decoder 50 receives the EDS data code from the data slicer 40 and decodes the data code to apply the data code through the data line of the microcomputer 60.

At this time, the microcomputer 60 compares the codes decoded by the decoder 50 according to the program according to the present invention and inputs them through a data line to be input.

At this time, the microcomputer 60 compares the code decoded by the decoder 50 according to the program according to the present invention and checks whether the data code to be input is EDS program length / elapsed time information (A, B). .

If it is confirmed by the above steps (A, B) that the program length / elapsed time information is checked, it is checked whether the elapsed time measuring mode is turned on, that is, whether the sleep function or the reservation watching function of the television is turned on by the user (C). ).

After confirmation, the program length data from the setting time of the sleep function key or the reservation request function is compared with the result time (D), and if the same is the same, the corresponding command is executed (E).

In this case, when the sleep function key is switched by the user, the sleep function automatically turns off the TV after a predetermined time, and stores the length / elapsed time of the program at the time when the sleep function key is switched, and continues. If the program elapsed time is inputted and the program length / elapsed time is the same, the television is turned off.

In the case of the reservation viewing function, when the program start time is set only when the user wants to watch a particular program, the end time is automatically set. The elapsed time continues from the start time of the program reservation viewing based on the program elapsed time information. Compare the program length with the elapsed time.

At this time, if the program length and the elapsed time are the same, the program is terminated, so that only a specific program can be watched accurately.

As described above, the timer method of the television using the EDS of the present invention uses the EDS data information of caption / text broadcasting to perform the instruction of the television after a certain time from the current information about the length / elapsed time of the television program. By using the time data for the effect that there is no need for a separate timer.
